I’m sure you have all been to a website to register and you get to the spot where they make sure your human by typing in the string of text in the box. right? Well this step is there not to see if you can read obnoxiously small numbers with a background that disguises the letters, but it is there to minimize accounts that would be created by bots. It has now been brought to our attention that this filter to stop bots might be UN-beneficial as of today, as researches have found a way to do it.
A team of Stanford University researchers were able to create a program that can read these annoying distorted letters. The algorithm Decaptcha works by detecting shapes and removing “noise” or distractions from letters. This allows their bots to sign up on many websites such as Blizzard, eBay, and Visa (Figure1). This algorithm can be dangerous because giving to the wrong people, it can de-purpose the point of these Captcha programs.
As you can see in the diagram, only google was able to completely stop Decaptcha from creating accounts.
Although Sanford says they will keep Decaptcha to themselves, they will allow companies to use it to test their Captchas. They say “Our goal is to make the Web a better place, not to harm users.”
Now that people are aware that these Captcha programs can be manipulated, it will arise talk as to what else can websites do to protect their users as I am sure many other people are going to try to create their own algorthim to bypass these Captchas.Now do you wish those string of letters were easier to read? I know I dont.
